Stage 2: Gneis - 1 battle. Top tier, had a friendly DD act as a screen in front of me to spot DDs. Worked well together.

Stage 3: Did the plane part in one battle defeat using the Cleveland. The damage part an extra 3 battles using the Warspite and Bismarck. (Fun fact: I've now won a record TWO games in a row with the Bismarck!)
